United States Patent | 5,330,099 |
Beales ,   et al. | July 19, 1994 |
An eat-in paperboard container for frozen or refrigerated foodstuffs is provided with lateral flanges and triangular sections at its forward two corners. The package is opened by a tear strip which frees an edge of the top cover for lifting and access to the foodstuff. In use, the triangular sections rigidify the tray when the top cover is ripped up to open the container and when the consumer grasps one of the lateral flanges during eating out of the container.
